Sensibilidad y especificidad de los estudios imagenológicos utilizados en el diagnóstico y seguimiento de pacientes adultos con COVID-19

Abstract

Antecedents: COVID-19 is a pathology of zoonotic origin, produced by a mutation in the coronaviridae family. Imaging tests have become an indispensable element in the prognosis and follow-up, through these it is possible to perceive the physical reflection of the patient's symptomatic picture and its evolution, providing benefits by determining a treatment with greater assertiveness in addition to preventing possible complications in time that are typical of the course of COVID-19 but very heterogeneous. General objective: To analyze the sensitivity and specificity of imaging studies used in the diagnosis and follow-up of adult patients with COVID-19. Methodology: Bibliographic review based on the compilation and analysis of different scientific articles found in search engines such as Pubmed, Science Direct, Cochrane, Medline. Results: The imaging studies that have been most useful in the diagnosis and follow-up of COVID 19 are Chest X-ray (CXR), Computed Tomography (CT), Lung Ultrasonography (LUS) and Positron Emission Tomography. The most frequent findings were ground glass opacities and consolidations. The sensitivity of radiography was 69% and computed tomography has a sensitivity and specificity of 67-98% and 24-94% respectively. Conclusions: Computed tomography is considered the gold standard; however, chest radiography was the most widely used due to several factors involved. Lung ultrasonography is positioned as a promising test for diagnosis and follow-up.
